The tool compresses valve springs so retainers and keepers can be removed or installed, while the air valve holding hose keeps valves seated under air pressure when the head stays on the block. Together they streamline top-end service on these popular V8 powerplants.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompressor design sized for the valve spring spacing and valve stem diameters used on LS series heads\u003c\/li\u003e\n\u003cli\u003eAir valve holding hose threads into the spark plug hole to pressurize the cylinder and hold valves closed\u003c\/li\u003e\n\u003cli\u003eAllows spring and seal replacement without pulling the cylinder head\u003c\/li\u003e\n\u003cli\u003eConstructed from hardened steel for repeated shop use\u003c\/li\u003e\n\u003cli\u003eWorks with standard shop air supply fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor GM Chevy LS series V8 engines\u003c\/li\u003e\n\u003cli\u003efor GM Chevy LS1 engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplacing valve springs, retainers, and keepers on LS cylinder heads\u003c\/li\u003e\n\u003cli\u003eServicing valve stem seals without removing the head\u003c\/li\u003e\n\u003cli\u003eCamshaft and valvetrain work in engine builds and rebuilds\u003c\/li\u003e\n\u003cli\u003eGeneral top-end maintenance on LS equipped vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTool Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eValve spring compressor with air valve holding hose\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine Family\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGM Chevy LS and LS1 V8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHardened steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Can I replace valve springs without removing the cylinder head? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, this tool set is designed so the air valve holding hose keeps the valves closed under air pressure while the compressor works the springs in place.
